This isn't a one time thing. For some reason I can't input a specific height distance anymore. This seems to have become a permanent problem.
This is the second time it has happened to me, the first time was on a different computer along time ago so i can't remember exactly how the problem occurred.

Hi,
I recently ran into a particularly annoying problem with Sketchup.

For some reason when i use the Push/Pull tool, Sketchup doesn't seem to recognize any distance/height I input into the Z axis (Blue).
However both the X and Y axis are still working fine when i specify a certain length.

Thanks for your time.
