Yesterday I installed Blender 2.75 on my Lenovo X230 with Intel graphics HD 4000.
Since the beginning I have been unable to select vertices in edit mode by clicking. Also the loop cut doesn't work at all (Ctrl+R, there is no purple outline and nothing happens after clicking).
I've got a friend who has some tens of hours spent in blender and he is also unable to do that on my pc. On his, however, it works like charm...
I also had some trouble with glitches in the gui, but it got solved by setting window draw method to triple buffering - indicating that intel HD drivers might be an issue.
I read about updating my drivers and that's what I did but was only able to update Intel hd graphics to version 22.214.171.12459 from 15.11.2013. Then, even if trying to update manually, my Windows 7 professional says it's up to date.
Any idea how to solve this?
