I have this problem in cuteeditor, which can be reproduced as following:
1. Create a table, for example 2 cols and 3 rows.
2. Type something in every cell
3. Double click the text in the cell to select all text in that cell.
4. Click on the "create link" button
about 80% of the time, the dialog will simply not load. This also happens when selecting the text using the mouse.
I've tried it in your example and here i have the exact same problems.
Any idea how this can be resolved?
Thanks in advance.
