I am using windows 10, what a piece of crap, but the mouse pointer is clear and easily seen until I move it onto the compose email screen in thunberbird, when it goes to a very faint, single vertical line that is very difficult to see in text, or it disappears altogether. I can not find any adjustment to fix this in windows or thunderbird, and it is so annoying, that I am going to be forced to quit using thunderbird, because impossible to compose emails when the location of the pointer can not be easily seen.

Hoiw can a fix this. Just alloow the p;ointer to appear in thunberbird the same as it does in windows would be a fine fix, but I suspect that is too simple to be considered, but that would be the best. Otherwise how to i adjust the appearance of the mouse pointer in the input screen of emails in thunderbird, so I can change it from the default which is impossible to see.
