Loading time of local courses

Hello,

I'm using PyCharm Edu(3.0.1) and I would like to test wether PyCharm is suitable for learning Python.

I'm using a network which does not allow to get the prepared Python courses (e.g. PythonIntroduction).

I have downloaded the course as a ZIP file and opened it as local project. The project works but the system is very slow.

For example it takes about one minute to load the task description and show the decription inside the window.

In case you have inserted a wrong solution of a task it takes about one minute until the "Check task" button is available again.

Can anybody explain to me why the system is so slow?

Thanks for your help!
