I'm quite sure that this is a conflict bug between Dock Manager and Toolbars Manager. It happens even when I've already updated to the latest version (2033). This is how to replicate the problem:
In a new form, add a Toolbars Manager. Add some toolbars and some tools.
Add a Dock Manager. Add two Panes: one docked to the left and one docked to the right (can use any controls inside the panes).
Start Debugging the program. Exit the program to return to VS. The Toolbars Component will disappear. I have to close the form and reopen to make it appear again. However, if I save the form after it disappears, the component will be deleted permanently from the form.
If I delete the Dock Manager then the bug is gone. I think the problem comes from the ToolbarsDockArea and UnpinnedTabArea, but it's just my guess.
One more question: when I group two or more DockableWindows in a Pane, when I unpin it, why can I see only one name.
I have the screenshots but don't know how to upload them here.
I was not able to reproduce the issue. I would recommend submitting a sample or detailed steps to the support group so it can be further investigated: http://es.infragistics.com/gethelp.

Set CompressedUnpinnedTabs to False on the UltraDockManager to see the captions of all tabs.

Click the 'Options' tab when composing a message. There is a button which allows you to upload an image.
I've been dealing with this issue for several months now as well. I have a form containing an Infragistics Toolbar Manager, Dock Manager and Grid. After loosing several hours of work on a few occasions and being forced to re check-out from source control, I've developped the habit of never leaving the design view of the form open in VS2005 while I run the application, as that will almost always cause something to disappear from the form. Sometimes it's the toolbars or the grid, lately (since I added localization) it's been all the localized text that will disappear.
Like in the OP's case, I can close the design view of the form and reopen it and everything will be fine, but if I forget and make a change that causes VS to rewrite the InitializeComponents(), then everything is lost and the only solution is to check-out from source control again.
I'm not sure if the problem is really with Infragistics or VS2005, altho it's only happened on this one form that relies heavily on a variety of infragistics controls.
For the time being, closing the Design view of the form before every Run does the trick, and maybe the problem will go away with VS2008, but in the meantime it remains an annoying concern that needs to always be on the back of your mind, lest you forget and loose a days work.
Yes, you have exactly the problem I have. Recently, I have upgraded to Visual Studio 2008 and Infragistics 2008.2, but the problem still persists.
