Lost regions

I run 4 windows with PiP:

1112
1113
1114

Picture 1 is the big one and 2,3,4 are tiled on the right.
I have hotkeys F1-F4 to call the respective wow's to the front. Hitting F2 will swap wow2 into the main picture.

Bug?:
If I mouse over window 2 and hit F1, it will move wow1 to that spot but it won't move anything into the main picture. So I'll have two small windows stacked on top of each other. At this point there is no way to get a window back into the big window without logging out an account relogging it. Even then I sometimes get an error that the window is no longer available.

This problem is at its worst when I'm in combat, mouse a little too far into one of the tiled windows and hit F1 (which is both a switch leader/main window/follow macro also).

It would seem there is some wrong behavior that an entire region is lost to use once something is moved out of it and not replaced.

Feature request/solution:
On the keyclone app, have a dropdown to select a region for an already running instance.

Any known workarounds or fixes?

your feature request already exists:

on your keyclone app select the wow instance you want to fix and right click it, select un-maximize. The instance will now be in a bordered window. Select the instance again in keyclone and right click it, you will be presented with a selection of regions you can put it in, including those that now are empty.

Oh wow, that fixes everything.

sweet ive stopped PiPn because of this messup thing, thanks so much
