Just wanted to report that v1.8.0.457 does install and seems to run okay on my Win98SE system with one exception. When closing the program, I get the Illegal Operation window. The program seems to close okay and then the winodw pops up. It is followed by another window with the message:
"Exception EAccess Violation in module jv16pt.exe at xxxxx (memory address). Access violation at xxxxx."
As an aside, I'm one of the users who has problems with previous versions of PowerTools but the problems were always eventually fixed. I'm running the "B" version of Win98SE (v4.10.2222B). FWIW, the "B" version just indicates that I installed the Security CD that MS distributed eons ago.
