Hello,
as I navigate my moodle, every 10 - 15 pageviews or so, the theme drops out, and all of the info on the page bunches up on the left side of the page.
I can get the theme to come back by:
1) Tools > Internet Options > Delete Files
2) F5 (refreshing the browser - Internet Explorer)
Note: I have accessed the moodle from a mac through safari and experienced the same problem.
Any suggestions?
