Generally UltraEdit will show “End of file, searching from top” when it reach end of file while searching text by F3 key.
But in guest os(Windows 10 LTSC 2019 and Windows 10 20H2) it cause BSOD.
I have tried on my desktop and laptop. Both of them have the same problem.
UltraEdit version I tested: 188.8.131.52 / 184.108.40.206
