Users have the ability to resize some of the windows within Sage, which is saved to their user profile. If a user on another computer has resized their window to go beyond the standard resolution you are testing, it could cause the above problem. Max out the resolution and test again. If the window appears, resize it to a smaller dimension and then switch the resolution back to the recommended setting.

Tried this - all users are getting the same behavior.

On these workstations - other workstations are fine.

What behaviour is Sage showing when you attempt to open these screens? The screenshot only shows the I/C Items window.

Sage "functions" you just cannot see what is in the fields.

Do the workstations have multiple displays set up? What I've found is some windows do not like to behave (no matter what resolution) if they are not on the same screen as the main Sage program. Also, sometimes they will not function when placed to a monitor to the left of the main desktop control. Try running Sage on the main display, and ensure the windows that pop up are on this page too. If that is the case  you'll probably need to raise this issue with Sage, as it seems to be a bug.
