I've been using this powerful Windows Explorer alternative for years, and have recently hit a problem with it that can possibly be solved by a smart bit of thinking. First off, no I dont know who the developer is/was. At one time it was Vcom but it got sold and development stopped at v.8. I still use v.6 and there were no further updates. I hear bad things about v.8 into the bargain, and have no intention of trying it, because the problem is probably fundamental. So this is the problem....it is not a functionality problem, it is odder than that. On a multi-processor PC, it can quite randomly happen that starting the program actually starts TWO or more copies, and neither of them is prepared to take responsibility for doing anything ! There is no interface. If I run task manager and stop one copy, the other may or may not suddenly appear. This problem is never seen on a single-processor PC, so my thought is simple - can I do anything on a multi-processor PC to ensure the application only tries to use one CPU core ??
