I tried to download an old community commons module in 2.5.6 but encountered the following problem: As you can see from the picture I am unable to select the buttons. Changing screen resolution does not help. The screen can not be resized and the buttons can not be reached. I can only close the button. I think this is a bug of 2.5.6. The way to solve this is pressing the tab button and enter. I hope this post may help some other person having the same problem. It took my some while to find the sollution and I do not think this can be fixed by Mendix. Regards, Ronald [EDIT] It happens with all versions of Mendix. Had the same problem yesterday with 4.2.
