After upgrading to webOS 1.4.0 our Pre seemed sluggish overall. Moving between the Launcher's panels is slower, and our Mail App was really giving us problems. We've finally managed to track down the Mail App issue.

If we have a Yahoo Account setup in the Mail App the App slows to a crawl. Sometimes it can take up to 5 minutes just to open the Mail App. We get a white screen that just sits there forever. Also, opening emails is very slow. It opens the email card, but the content of the email takes very long to fill in.

It seems that either our Yahoo Mail account was corrupted during the update, or webOS 1.4 doesn't play well with Yahoo Accounts. We're guessing our account entry is just corrupted, however deleting it, rebooting, and re-entering the account does not help. If we simply delete the Yahoo Account and keep our existing Gmail Accounts, the Mail App works like it should.

We haven't had a good experience with Palm's latest 1.4 update. This is the first time we've experienced issues with any update from Palm and it's very strange. Other users are talking about problems, but not enough to cause other gadget web sites to report on it. What does this mean? Who knows, but we hope Palm issues another fix shortly.
