Fritzing is very slow on my PC

For me your fzz file doesn’t load

If I ignore the error the sketch appears normal for me (Fritzing 1.0.2 on Win10.)

Although it looks a little odd (probably due to the missing part.) There is probably an error in the adafruit_Permaproto_Full_sized_board part. If you upload the .fzpz file for the part I will have a look at it.

edit:

A post from 2018 reported a similar problem but I was never able to reproduce it to fix it. I see someone later posted a new set of boards at the bottom of this thread which may help. As I said if you upload the .fzpz file I’ll have a look at it and see if I can reproduce the issue and fix it,
