We have a primary application which calls a secondary application. The cute soft editor is in the secondary application. The secondary application is opened using a call of "window.showModalDialog(URL, "", Param);".  When it opens in this mode, everything works fine until the more colors dialog is opened, or Ctrl-Z / Ctrl-A is pressed. The more colors dialog generates a javascript exception and then exits, and Ctrl-Z / Ctrl-A are ignored (even though they are configured as hotkeys).

When we open the same secondary application in a regular browser window, everything works fine and we have no problems.

Awaiting your response, thanks.
