Pressing F1 makes R4 crash

I saw this error on a foobar forum somewhere and I thought I would try it out to see if it was true and it is.
I only have 2 presets in my directory atm and using v1.09beta but it has been reported for other versions too.
Yes pressing F1 to toggle between full screen and windowed mode makes it crash press it a pfew times in quick succession esp while it is loading.
And you get:
R4.exe has encountered a problem
AppName: r4.exe AppVer: 0.0.0.0 ModName: r4.exe
ModVer: 0.0.0.0 Offset: 00041102
Maybe a buffer to check to see if the F1 is been pressed multiple times or disable it whilst it is loading up.
