Version: 4.0.0261
Platform: .NET 2.0
Environment: Windows Vista (32-bit)
Under Vista the scroll wheel doesn't work. This bug has been reported before, but it seemed that it was dismissed as due to a problem with the mouse driver.
I tested two mice. One was a Bluetooth mouse (Microsoft Wireless Notebook Presenter Mouse 8000): if I scroll very quickly on the wheel, the editor will sometimes jerk a little in the right direction, but it isn't useable. The other was a standard USB mouse (Microsoft Optical Wheel Mouse): I couldn't get any movement at all.
Environment 1:
Lenovo ThinkPad T61p
Windows Vista Universal 32-bit
Visual Studio 2008 beta 2
Steps to reproduce under environment 1:
Launch C# Demo Project. VS2008 performs conversion of project without problem (one file was not backed up). Launch project, then launch SDI Editor. Try to use scroll wheel in main editor pane - fails (for both mice, as above). Click several times in main editor, to generate text in Events pane so that scroll bars appear. Try to use scroll wheel in Events toolpane - works flawlessly.
The same pattern is true in my own application. All windows except SyntaxEditor work without problem.
I verified that the demo project still targets the .NET 2.0 runtime after conversion, and that all referenced DLLs were 2.0.
Environment 2:
IBM ThinkPad T42
Windows XP SP2
Visual Studio 2005
Steps to reproduce under environment 2:
I compiled the demo on a Windows XP machine running VS2005. I launched and verified that the scroll wheel worked in the editor (it did). I then transferred the executable to my Vista machine, launched it, and got the exact same problem as above (with both mice).
I should add that no other application has had problems with the scroll wheel under Vista.
