Left-handed mouse crashes Pentagon

I thought I would post this information in case there are any other people out there using the mouse with their left hand and wondering why Pentagon keeps crashing. If I use Windows 7 control panel to reverse the left and right buttons on my mouse, Pentagon (DX version) crashes when I use the mouse to move the knobs on the interface. This happens consistently in both Sonar X3 and Reaper, making Pentagon unusable. When I switch the mouse buttons back to their default assignments in control panel, the synth works just fine. I'm glad I figured this out. I like Pentagon and can live with using the mouse right handed while I'm working with it.
