I am using the CSOM of WebSpellChecker to find all controls on my page where the attribute SpellChecker == "True" and performing spell check on them. Because everything in the application is contained in at least one update panel (and the dialog WebSpellChecker attempts to create by default apparently doesn't work with UpdatePanels) I had to create a separate page with only a WebSpellCheckerDialog control on it.
However, when checkTextComponent(id) is called on my spell checker, each individual control gets its own popup window. How can I make the spell checker use the same dialog popup for all the controls being checked?
