Error Processing Clipboard Event: Invalid Parameter

[cnewtonne]

Never seen this before. Started happening after updating to 5.4.0.2.

I did not notice what triggered it. But, once it happens, every time I hit ctrl+c, this error message pops up.

It does not matter what app I copy from, UR immediately returns this error.

From that point forward, I can not copy/cut without get this error message from UR.

Only way out is to restart UR.

Thanks
