Sorry no one has gotten back to you yet. I believe this is a known issue (a forum search would confirm that but I don't have time right now), and I believe it will be corrected in a future release. You can try 2 things in the mean time. 1) Try running OpenLP with administrator privileges (right-click the shortcut and select it). 2) If it still persists, you can disable Windows from automatically generating a crash report (google it - sorry I don't have time), but just be aware that will affect all applications that crash.
