Object selection tool not showing up?

Hello,

Issue is in the title. When I click and drag with the selection tool, the rectangular line showing your selection area isn’t showing up. This seems to come and go randomly. The past couple of weeks it was working fine, but now and a few weeks before this it isn’t/wasn’t showing up.

If anybody could help me with this I’d be most appreciative.

Thank you,
Randy

You’re not running Synergy, are you, by any chance?
