User Agent: Mozilla/5.0 (Windows NT 5.1; rv:6.0.2) Gecko/20100101 Firefox/6.0.2 Build ID: 20110902133214 Steps to reproduce: Composing a message. Actual results: I get interrupted while typing, whenever Thunderbird saves message to draft. The whole application stops responding. This started happening since version 6. I am using WinXP 32-bit. Expected results: Saving to draft should not freeze the application.

AppleGrew, is it hung with high CPU? Please start thunderbird in safe mode using instructions at http://support.mozillamessaging.com/en-US/kb/safe-mode ... If safe mode is not better, try temporarily disabling your antivirus software. If safe mode does work better then: - go to the Config Editor. In Thunderbird do Tools → Options (or Preferences) → Advanced → General tab → Config Editor - paste gfx.direct2d.disabled into the filter - double click that entry, to change the value to true - paste layers.acceleration.disabled into the filter - double click that entry, to change the value to true -- if layers.acceleration.disabled does not exist, please create it -- right+click in the preferences area and do New | Boolean | paste layers.acceleration.disabled in to the name -- set to true - restart thunderbird * If the video toggle doesn't help, then test to determine which addon is causing the problem. Please post your results

It does hang with high CPU. When save to draft is complete then it is back to normal. I didn't log into Safe mode, but in normal mode disabling the above options, seems to fix the issue. To replicate the issue. Open the compose message window -> Type something and wait for the autosave to kick in OR Manually click on Save (to Darft) -> Click Cancel on the saving dialog and then click Retry on the next dialog.

thanks for the feedback
