I'm surprised that there have not been more postings about this problem. I use Firefox and have been having an awful time with logging on ever since the new software was installed.
In fact, the only way to get a board to load is to click on a different board. That gets the board I want to load to finally show up, then I have to do a page back to get from the new board to the one I originally wanted.
If the new software is supposed to load faster, it certainly isn't doing it for me. I can't believe I'm the only one experiencing this.
