Schwertz: I took a quick look into the source code. And the problem, most probably, is not a screen resolution but the fact that HiRes patch and touchmouse.dll tamper with the same part of Fallout engine. It would be wise to contact Mash via NMA forums (nma-fallout.com/forums/fallout-general-modding.18) and politely ask to provide compatibility. Or even to integrate touchmouse.dll code into the patch if license allows.
