I'm doing a fresh install without any imports to see if that fixes it.
Update on fresh install, sadly trade - hide worked three times before it hides the main UI. Had to ALT tab to get it back.
Will change a little for the next release, so I hope your issue could be gone. But last question:
Is there a version of TCE, where you didn't had this issue, or on which version the problem arise?
Or did you changed anything on your side, like a new monitor, drivers, etc. and thereafter the issue appear?
Could you include instruction in the manual for uninstall it does not appear in the 'Programs and Feature' dialogue window?
In an attempt to correct an error I opterd to install the new release and it was better, but wish to uninstall it and try again.
Sure will add a note for uninstalling TCE to the manual, but it is quite simple. You only delete the install folder of TCE.
