Debugging is very slow on my laptop

[matze]

Hello, I have a problem with Pelles C, version 9.00.9.
Debugging a win64 GUI application is very slow; each execution step takes a few seconds: the current line is executed quickly and jumped to the next line. After that, Pelles C is occupied with itself and is not usable for me for a few seconds. In version 8, this problem does not occur so far, which is why I have not yet used the latest version of Pelles C to work. I have a laptop with fairly slow processor (Pentium Silver N5000) and Windows 10 Professional.

Check running addins.
Last release of PellesC IDE activate all addins it found after installation.
Some demo addins slows the IDE, especially the "debug interface demo" that nails down the debugger.
Go to menu: Tools->customize, in the tools window select the addins tab and deselect the unknown, or unwanted addins, restart the IDE.
It should run correctly now.
