User icons in GIF format seem to display at a very low quality in Twitterrific, as compared to jpg and png icons.

I have some stange problems with Twitterrific:

Sometimes (actually most of the time) when I activate the program, either from the dock or from the Menu Item, the window shows up correctly and I can skim through the unread tweets with my space bar.

If, however, I want to tweet myself, or click a link in a tweet, the GUI misbehaves. When I click into the text entry field, the cursor appears there, but it does not blink. When I start typing, nothing appears in the field - until I click again, then it all appears at once.

When I click around a bit, or click the refresh button, sometimes it suddenly works again properly (with correctly blinking cursor bar etc.)

Same with links, it sometimes needs multiple clicks to get it to open.

I guess this problem is caused by an interaction with some other Software on my computer, but I could not find out what the problem could be. Any hints?

For some time now, I'll mark all tweets as read yet still get new tweet notification via the menu bar icon -- though there are no new tweets. This will happen a dozen or so times a day for me.

I've tried deleting prefs and cache to no avail.

When I start Twitterrific, I get the message:

"Twitter Error
There was a "HTTP 304 response" error while communicating with Twitter. This is a problem with their server, so contact Twitter at ... if the problem persists."

The log says the error occurs fetching the timeline of people I follow. When I post a new tweet myself, the error goes away the next time Twitterrific refreshes.

I know this is labeled Twitter's problem, but I'm not sure it is. Aren't 304 Not Modified responses normal when requesting tweets? It seems more likely that I'm trying to use Twitterrific with lower Twitter traffic than most people, and Twitterrific is confused that there are actually in fact no new tweets in whatever time frame it's asking about.

Has anyone else had this problem?
