Remote Connection Manager (RDMon)

For those who use Remote Desktop Connection Manager, v2.93

I'm trying to utilize the feature of Hot Keys.

From the menu -> Tools -> Options -> Hot Keys (tab) -> Previous session.
I use the ctrl-alt-insert for full screen all the time.

Problem is the ctrl-alt-rightarrow / left arrow are not working.

I'm expecting it to cycle to the next open VM.

I've used this in the past but now it doesn't seem to work anymore.
