Hello and welcome to the .LRN forums Hasan! Thanks for the feedback.
I have recently reported both of these problems:
https://openacs.org/bugtracker/openacs/bug?bug%5fnumber=482
https://openacs.org/bugtracker/openacs/com/bug-tracker/bug?bug%5fnumber=472 (I agree that we really need a simple way to search the bugs)
Peter, I checked the test servers before posting the .gif bugs. Still not fixed. On the page Hasan mentioned /dotlrn/ is missing the img src of the spacer.gif. In one case it seemed to be a permissions problem.
