Too delay in the stack mouse viewer

I have a problem with the viewer. The delay is about 10 seconds when i put the pointer in a counter. The map is an hexagonal grid and i have the same problem to view the number of the hex (about 10 seconds until it pop up). I have changed the delay in properties to 1ms and the result es the same. I only have the problems in my notebook. My other PC doesn’t have the problem. Both have the same RAM. Both have different resolution screens. Any opinion?
The module is SPQR:
