I'm running Map Monkey 1.1.348 embedded in RoadRunner in advanced GPS mode. Using Xport3.
I was experiencing occasional crashes from GTXP.DLL, did a search, found the beta dll referenced Where to download Fixed Gtxp.dll named Gtxp_beta.dll.
When I swap that DLL in, my CPU usage shoots up to near 100% and everything slows to a crawl. Map monkey works, but hangs when trying to close the program.
Of course, reverting to the other DLL invites the crashes to return.
