Frustrating mouse scroll issue.

OK as I suspected, this is a problem on my end, though it DOES seem specific to Reaper. No other programs have an issue like this. But when I installed Reaper on another computer (my future DAW, to be exact!) scrolling with the mouse wheel works as expected (as I figured it would.) Even after removing all traces of Reaper on my current computer (which is thankfully very easy to do) and then reinstalling it, it still has that scrolling problem. So something's off somewhere. It's a pain but I can live with it a little longer... I'm just dabbling at the moment cos I'm not quite prepared to move to the new computer yet, but now I've got even more incentive to do it as soon as possible. So yeah. Even with this issue, I'm loving working with Reaper and adapting to it! (I'd still appreciate it if anyone has any ideas on what might be interferring with Reaper's response to the mouse wheel.) tks

On the problem PC, try renaming your reaper.ini file (this is not removed during uninstallation so that your preferences / settings can be remembered). The file is in C:\Documents and Settings\DarkStar\Application Data\REAPER here. Reaper will create a new one when you next start it. HTH

Hi Darkstar and Gopher. Thanks for the replies. I had actually tried deleting/renaming reaper.ini earlier. It cleared out all my settings, but the mouse wheel problem was still there. So it seems to go deeper than that. The only other mouse I have is the identical model to this, and it behaves the same way. But digging around in the advanced mouse driver settings in Control panel, I was able to semi-solve the problem: When I added reaper.exe to the "disable IntellPoint wheel support" list, the matrix and MIDI editor started scrolling correctly. But I lost *all* wheel scrolling in the track 'item' area of the main window (the track control panel on the left still scrolled correctly.) Strangely, there were already 5 applications in that list, none of which I actually own... the closest I come to any of them is Internet Explorer 5.0 (yes, that's 5.0! :)) Those must've been automatically set when I originally installed the mouse driver, so the problem I'm experiencing with Reaper would seem to be at least somewhat related to this known issue. There's an updated driver to the mouse, which I can imagine would fix the problem. But the driver verson I'm using lets me program it so that clicking the wheel sends a "Spacebar" command to specified programs, like Reaper and Sonar, which lets me start and stop the transport from the mouse... which is REALLY convenient and I'm addicted to it. But the newer driver for some reason omits the spacebar from the list of available keys that can be assigned to the different buttons. :( So I reverted. (Maybe a Reaper action would let me program that directly...? Have to look into that.) I guess I need to figure out which compromises I'm willing to make. But what else is new? hahaha Thanks for the kind welcome, Gopher. I'm finding Reaper too compelling to resist, learning curve and all, and I'm looking forward to using it "for real" and trying some from-scratch projects on it when I finally move over to my new computer. Thanks again for the suggestions!

I'm not sure if my problem is related. I'm using an IBM mouse that doesn't have a scroll wheel, but rather a sort of blue button that acts like a little joystick (it can rock in X or Y directions) With other Windows Apps, this allows me to scroll a screen up or down AND left and right. However, it behaves strangely in the Reaper Mixer window. Rocking the button left or right scrolls the contents of the mixer window left or right (great for when you have more mixer channels than can fit on screen). However, when I hover the mouse pointer over top of a channel's volume slider, I expect UP and DOWN on the mouse scroll button to raise and lower the track's slider (like a scroll wheel does). Instead it ALSO scrolls the window's contents left and right.
