  Detecting modal dialogue box

  Posted by Reuben Lara on November 23, 2019 at 2:20 pm

  How can i detect if a modal dialogue box is open? This error: “Cannot run a script while modal dialogue is waiting for a response” appears under the following condition:

  1. Open my ScriptUI panel
  2. Open a modal dialogue like “Import”
  3. While the dialogue box is open, hover over my ScriptUI panel if it’s showing in the background.
  4. The error triggers.

  My panel uses a mouseover event so it makes sense why the error is triggering. But how can I get my panel to ignore mouseover events when a dialogue is open?

  Thanks!

  Hey Reuben, not sure whether it will be beneficial – but what about beginSuppressDialogs() and app.endSuppressDialogs()? It allows ignoring them completely, but might not work in this case.

  Hi Reuben, happy new year! i’m experiencing exactly the same problem, did you have any luck using the suppressDialogs? I’ve tried this within the function called by the mouseover event listener, but it’s still causing the scriptUI to freeze. Be great to hear from you, thanks!
