The openpanel object on WinXP and Pd 0.39 causes Pd to exit randomly. It doesn't crash, and the debugger says it simply exits with:

The program '[4032] pd.exe: Native' has exited with code 1 (0x1).

I haven't found any real pattern to this other than doing more than a few seconds of searching will trigger an exit. File browsing is somewhat futile.

Any ideas?
