Loss of pinned tabs

I note that this problem has been going on for more than 5 years and is STILL a glitch with your otherwise excellent product! Strangely it has only started happening to me though since I got my new PC. It really shouldn't be beyond you to provide an update with a permanent solution rather than having to close a window before it is saved as suggested on a 5 year old forum.

Please fix this now - 5 years is a long time in the IT world!!!
