XRoar-0.34.5-w32 Problem

In XRoar-0.34.5-w32 something isn't being reset properly whenever a hard reset is used, and whatever it is is causing the emulator to crash if it tries to display certain screen/pmodes. I do not know if this bug exists in other versions of XRoar.
To demonstrate, start XRoar, perform a hard reset (either via the menu or by pressing Ctrl+Shift+R), and then type the following:
10 PMODE0 (or pmode 2 - the other pmodes work fine)
20 SCREEN1,0
RUN

Thanks Ciaran, that was quick work!
Initial tests suggest that the fix has solved the problem.

Cool. Wasn't the NTSC code after all, but something related to it was being overwritten by normal scanline generation (specifically the case where you switch from a 32-byte to a 16-byte mode mid-scanline, and then get a far-too-long line before HSync).

and the *far too long* line is a nice trick to push stuff past the right hand border...
and we know this works on real hw too
