We asked you for a backtrace, and told you how to get one, but you weren't able to provide one. Also, you didn't give a complete recipe. Both of these make it harder to help.
But I finally reproduced a crash as follows: wine Wabbitemu.exe choose "Create a ROM using open source software", click 'next' choose default "TI-83 Plus", click 'next' chose default OS, click 'next' type random filename, click 'save' click on the central green area and drag. When you release, it will crash:
And here's the short log: fixme:shell:IDropTargetHelper_fnDragLeave (0x142880)->() ... 0009:Ret ole32.DoDragDrop() retval=00040100 ret=00442e9f trace:seh:raise_exception code=c0000005 flags=0 addr=0x442ea3 ip=00442ea3 tid=0009 ... wine: Unhandled page fault on read access to 0x00000000 at address 0x442ea3 (thread 0009), starting debugger...

So it seems there's some problem with our drag and drop support... unless the app also crashes on drag in MS Windows, which I didn't check.
