I've just been playing with the latest version of the Turbo compiler with intent to verify compilation of PCB Design. However whilst compilation completed without warnings or errors, there is an odd issue.
I'm running the compiler on the latest QPC2 and the compiled program worked well but bombed out when QPC's screen resolution is set to 512x256. The error was:
*** Task test_task halted, after line 0. Reason: value out of range
I've now determined this occurs when compiling any program and running it with a screen resolution significantly lower than that used whilst compiling.
The workaround is always compile in 512x256 which results in programs that are happy at all resolutions of QPC.
I've probably just misunderstood something, but would like to know what

Cheers,
Malcolm
