Reaper mouse cursor issue

Hey all I figure this should be an easy fix because I don’t see any threads on it.

But when I enter my plugin from the left, the cursor inside my plugin gets “stuck” as the left edge resize cursor. I have to enter from a different vantage, or move my mouse rapidly, in order to have the standard cursor inside the plugin.

I tried using getCursor and setCursor within the editor to force a standard cursor but it’s not working. Any ideas? Thanks.
