there is a discussion recurring from time to time about PyCharm hanging on startup at scanning files. It is not a real "hang", tough, it seems more as if PyCharm is trying to load Framework-data recursively. There is no thread-dump, because is does not crash, but after a while, it tells me that memory is running low.
I did not find a solution for this, even not in this support forum. Any ideas highly appreciated, since I can't use PyCharm currently.
