Maps with very large dimentions may load slowly or not at all

This popup message appears whenever the Page Toolbar Menu for a 100x100 unit or larger size map is accessed with either Chrome or Firefox as GM. “Maps with very large dimentions may load slowly or not at all. Do you wish to continue?” The only way to get it to go away is to shrink the map to 99x99 units. If you persist through several of these messages and press continue, this new message appears: “Prevent this page from creating additional dialogs?” As I understand this is a Java script message issued by Chrome or Firefox browsers when they encounter a popup alert message stuck in an infinite loop. An answer of yes to this prompt gets rid of the “very large dimentions” popup but causes the Page Toolbar Menu for that tabletop page to lock up permanently. I cannot edit or even delete that tabletop page after this occurrence. This is not a surprise, as that message is intended to lock out malfunctioning dialogs that will not allow you to exit a page. I can track this situation back at least 3 to 4 weeks, which makes me suspect it came in the last update. One other gamemaster also reports this same problem. It seems to affect sound as well. Can anyone reproduce this issue on either browser by simply creating a 100x100 unit map and trying to use the Page Toolbar Menu? There are other tests I can try with this issue and will post anything discovered. Thanks

AFAIK, this is working as intended. The map size warning was put in because a lot of players were being locked out of their game after creating a map that their computer couldn't handle. 

I only wish to know how to turn the message off, so it will not trigger the lockup problems with the Page Toolbar. I use large maps only as simple battle maps where the long ranges of Pathfinder long range spells, heavy xbows and ballista come into play. The pester popup is the only problem I have encountered and I doubt the developers wished to inflict those problems on paid subscribers. My maps worked fine until this message began appearing.

As I'm understanding it, the prevent additional dialogs pop up is what is locking your page navigator up. Just don't allow it to prevent additional dialogs. The page size warning is a fail safe there to stop people from locking themselves out of their campaign and isn't, by its self, lockign up your page navigator.

After you sit through that message 30 times building a tabletop page you want the popup and whoever programmed it to take a long vacation in the 9 Hells.

A paid subscriber is asking how do I disable that message so I never see it again EVER.
