Problem with JQuery UI Modal Consistency

Problem with JQuery UI Modal Consistency


I've worked on an application that's made extensive use of UI. I'm
having some issues. I have tried everything to make the modal window
open the same size each time. I use the modal window in numerous
places throughout the page. Here's the behavior:
The first time the modal window opens it opens exactly the same size
it should be. Let's say 600x800 is my default setting. The first time
it opens up as 800x600, the second time it's a different size. The
third time it opens, it's 600x800, the fourth time it's a different
size.
I have no idea what to do to fix this. I've tried so many things,
changing things, changing to a non-JQueryUI modal window and
everything else. I have no idea what to do and my client is furious.
Is anyone out there able to help me with this problem, I would be
happy to provide the URL if you're willing to help.
