It wasn't until I read this that I realised it used to happen to me all the time and annoyed the hell out of me, but it then stopped for no apparent reason. 

For the last few months I have been using 'Slim Parameter Panels' by Netherworks which I find great and I cannot remeber this problem while using this.  Not sure if this is a coincidence but I do find the Panel useful when there are a long list of parameters available.

 

 

I use Poser 13 on Windows 11 - For Scene set up I use a Geekcom A5 -  Ryzen 9 5900HX, with 64 gig ram and 3 TB  storage, mini PC with final rendering done on normal sized desktop using an AMD Ryzen Threadipper 1950X CPU, Corsair Hydro H100i CPU cooler, 3XS EVGA GTX 1080i SC with 11g Ram, 4 X 16gig Corsair DDR4 Ram and a Corsair RM 100 PSU .   The desktop is in a remote location with rendering done via Queue Manager which gives me a clearer desktop and quieter computer room.
