@nagesh007 We've tried to reproduce the issue be we couldn't observe the behavior you described. Are you still encountering this issue and can you provide any more information to help us diagnose it? Thanks!

@Stefterv Actually, I was able reproduce this on Windows 10. The PDE becomes unresponsive for a rather long time upon launch and when saving a sketch. In that second case the text "Saving..." appears and hangs there until done.

Note: during this time, key inputs are buffered and appear correctly once the PDE starts responding again.

The issue doesn't seem to exist on Windows 11.

Ah cool, how about 4.3 ?

@Stefterv Actually, the issue also exists in 4.3.

https://github.com/Stefterv/processing4/actions/runs/12470958462 Can you try the gradle version :)

I just re-triggered the build so give it a sec to show

I just tested on a fresh Windows 10 VM and didn't see the same issue

We received a report of a similar sounding issue on Windows 11 on the Processing forum:

When i open processing and then open a file Processing freezes for about 1 min. This happens every time i want to open a file with Processing. It has gotten really annoying. Does anyone know a fix? I’m using processing 4.3.1, windows 11.
