SingleStep with F7/F8 hang IDE

[Berocoder 10]

Hi, I am using latest delphi with all patches. Delphi 11 Version 28.0.46141.0937

When I debug my application by singlestep code with F7 or F8 sooner or later I cannot continue.
IDE is still responsive but programcounter hang and singlestep code have no effect.

I have seen this problem before also with previous 10.4.

Anyone with similar experience ? What can I do as workaround except to restart my application and try again.
It seems to be completely random...

Sometimes I get the Fx keys to lock up. Try to unlock them. I have a "Lock" key for that

Ok, but I don't understand what you mean. My F-keys works find outside Delphi in this case. What is a "Lock" key ?

I couldn't find a better picture.

This happens frequently for me too, even though I rarely use Delphi 11. That's one of the bugs that keep me from switching to Delphi 11 for anything serious. And no: For me this is not Fn-key related (even though that's a valid point), mine is a desktop computer with a regular keyboard that does not have any "media" related key remapping.

Ok, I have a Scroll lock key on my keyboard. I can try that next time it happens. I hope there is a bugreport on this on https://quality.embarcadero.com

Are you working on a 32 or 64 bit target?

Mh, never had a problem with those, but my projects are small to medium since i'm retired and use no 3rd party controls.

You can still use CPU view to get 'the iron' as the Late Danny Thorpe would say.  

 

This stuck my f7 and f8 Keying in CPU view stepping through Tee chart update without source.
