I would appreciate if you could try the command in Maxima (and report which version of Maxima is being used).
I don't have this problem but I use linux and a slightly older wxMaxima version.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Sorry,
I'm using wmMaxima 14.12.1 on Windows7 x64 edition.
Not in Maxima 5.34.1 :
(%i1) a:sqrt(b^2-4c(d-e));
2
(%o1) sqrt(b - 4 c (d - e))
Thank you.
I think, it may be a problem in the wmMaxima.
I'm not having any problem either with wxMaxima 14.12.0.

This is the evidence.
When wmMaxima freezes, its process seems to consume an entire CPU core.

I'm using wxMaxima 14.12.1 and Maxima 5.35.1.2, the latest version for Windows.
This problem doesn't seem to happen with other frontend. XMaxima.
Thanks, I've reported the bug at https://github.com/andrejv/wxmaxima/issues/424.
I guess we can close the issue here.
Problem apparently fixed in the git version so the next stable version should have it fixed. I think it's safe to close this thread.
Thank you!
I await the next stable release.
I'm closing this as wont-fix since the issue was in wxMaxima.
