Using KM on English Windows98
When I open a lot of layers (20+), not surprisingly KM starts to consume more and more ressources (as indicated by rsrcmtr.exe). Unfortunately, these ressources are not released upon closure of individual layers. The only way to recoup the ressources is to exit KM. But my impression is that even exiting KM does not release 100% of the ressources previously consumed by KM.
It appears that when ressources get below the 15% level there is a greatly increased danger of the display bug as recorded in bug 315
