mouse not letting go of tasks when moving

I’m using Firefox 2.0.0.13 and a boatload of extensions, and something seems to be preventing the mouse from letting go of tasks in the agenda view. I can drag the item over and release the mouse button, but when I move the cursor away, the item continues to move with it.
I disabled Greasemonkey to see if it was a problem with a script, but this solved nothing.
Are there any extensions which have known problems with Mentat? It’s going to be a pain to disable them one by one and restart to get to the root of the problem, so I hope that this can be avoided. Thanks.

Here are the extensions I currently have enabled:
Adblock Plus
AideRSS Google Reader Integration
Better Gmail 2
BlogRovR
BlueOrganizer
BuyLater
CLEO
CustomizeGoogle
DOM Inspector
FEBE
Foxmarks Bookmark Synchronizer
Google Gears
Google Notebook
Greasemonkey
GTDInbox
iMacros for Firefox
Interclue
LinkedIn Companion for Firefox
Mouse Gestures
OpenBook
Session Manager
Smart Bookmarks Bar
Tree Style Tab
Xoopit for Gmail
All of these have been updated to the latest versions.

I am having the same issue, along a number of other things. I don’t use half of these extensions.

Hi,
I am runnning Mentat under Firefox 2.0.0.13 currently and trying to reproduce that error. I have not seen it happen yet though.
If you can give me a detailed step by step on what led to the error and I’ll retrace it it on my end.

Also, hmsloyd, if you see any common extensions that both you and mdenner are using, please let me know and I’ll investigate.

erik,
I went through and disabled a number of extensions and the error seems to be linked with AdBlock Plus.
I still am not able to drag an item from the agenda to a specific project, however. When I drag an item over, it seems to just get dumped into the top folder and then I have to select the project with the drop down menu. Is this normal, or could it be another issue with my extensions?

Erik, I think mdenner found the solution. I disabled adblock and so far it has solved this and several other of my problems.

While it’s true this solved my immediate problem, ideally the two would be more friendly with each other. I don’t know if this is something that can be fixed with the Mentat site or not, but this is the only site where Adblock has given me trouble.
Also, I am still curious about my other question. Is it normal for Mentat to just dump tasks back into the top project folder when dragging and dropping?

*Thank you guys so much for your efforts and for discovering the trouble with the Adblock plugin. We really appreciate it. We will be looking into a solution for the plugin issues.
*If you are trying to move tasks between projects, you can’t just drag & drop into a new project as it works currently. The task will only drop back into its project of origin. If you click on the i and open the task information though, you can then click the project name in the upper left and it will bring up a dropdown selector that will let you change what project the task belongs to. After you’ve selected the new project the task belongs to, you can drag it in to that project. You may have to refresh the screen to update your projects after changes.
*I hope that helps and thanks again for your active correspondence.
