Hi Jose Luis,
We have not encountered such an issue before and were not able to reproduce it with the Q1 2011 (2011.1.315) version of the controls.
The only thing special about the table dialogs is that they can only be shown when the caret is positioned inside a table. When the caret is not inside a table, the ShowTablePropertiesDialog and ShowTableBordersDialog will not be opened. The respective commands for showing them will not be executed, whereas the methods will throw an exception.
If you have enabled library caching, none of the dialogs will work. You can ascertain that by trying to show any of the other pop-ups like the SelectionMiniToolBar (which is shown when you select some text), the ContextMenu (shown on RightMouseButtonDown), InsertHyperlinkDialog (RightClick->Hyperlink...). If neither of those work, you would need to manually instantiate them, as done in the TelerikEditorExample constructor in our online demo
. You can preview the code by switching to the Source tab in the top right corner.
In case that does not help, we would appreciate it if you could send us the project in a support ticket.
