occasional odd behavoir

Still occasional odd behavoir using Black Seesmic site. Auto refresh not working. Video quality appears inconsistent, no specific time of day or number of other users on service. time. Some videos I have allowed to auto play for confidence after recording never made it to public time line or to Private message. Total number unknown, do not think it is many (guessing 5-10). Last night may have been most. Learned of easy work around using view Profile to avoid show/topic refresh problem.

Reminder:
Inbox notification inactive?
Scroll wheel on a Mac never worked but does on PC's to navigate Public as well as following, inbox and sent time lines.
