Searched forums to-day for a problem I had about posts taking forever to go thru but most of the time they would just freeze, or time-out and leave me looking at a blank page.
The answer to my problem was so simple that I feel embarrased to mention it. It was just spyware (43 in total) that I had on my computer. Cleaned them out and bingo... nice fast posting again. Brought the subject up because I'm sure other bloggers must have the same problem from time to time.
