I’ve been having similar problems, but the problems change. For example, I found that pressing F12 to open a page in a browser was opening the same page many times - probably up to 20 or 30, but it varied. However, if I clicked on design view, only one page was opened; the problem only occured if I was in code view before pressing the button. I could reproduce this reliably, until I restarted Wapper and the issue has gone for the time being.
I’ve had similar problems with the shortcuts I use most: Alt+ F and S. The first thing I do when I open Wappler is press Alt+F to display File Manager. Recently it hasn’t been working initially, but only after trying a number of times (unless I give up and use the icon). However, it seems it will work reliably, as it always has, if I click onto the design view panel first - which is related to the other issue I mentioned.
At the moment, my cursor is in code view and none of the critical keyboard shortcuts work: Alt F, S, G, T etc. and Ctrl+Alt+F. If I click onto the design view or App Structure panels, they all work reliably.
