I am having a problem with PyCharm (Community Edition) in that, when I open a .py file in the program, I can happily read and write in the file as usual, however when I click out of PyCharm (to look my emails for example) and then click back into it to carry on with my code, the file automatically closes and the project tree structure collapses (so I have to re-open it every time).
So far I have tried changing the tab limit to a high number, but this doesn't seem to help (and it shouldn't be related, since this happens when I open just one file).
Any help is much appreciated!
