Comment 5 for bug 1767848

Is there a footprint viewer in the symbol chooser dialog? Or do you mean the symbol previewer window?

I attached a Zip file in Comment #1 containing three files (and a bunch of layers of directories -- sorry!). One of them is a screen shot of the Choose Symbol dialog taken while KiCad was locked up. Maybe that will answer your question.

You might also want to look at the backtrace (stack dump) also included in the Zip file. It may tell you what KiCad was trying to do while it was hung.
