A Bug Report:
I use Windows 10 and TeXmacs 1.99.5.
I try to export tm file to a pdf and replace an exist one:
1. When the exist pdf is closed TeXmacs works fine.
2. If the exist pdf is open when I try to export, TeXmacs will show an error emssage: "Error: failed to start PDF", which is reasonable. However, when I click the "clear" button and try to close the error messages window, I see a Runtime Error, and then TeXmacs crashes.
Thanks,
Jian
