It sounds like you've already found the problem. If the crashing stops whenthe plugin is disabled, the problem is in the plugin and there's nothing you can do in ID that's likely to solve it. That's up to the plugin vendor.
At first it does appear that the plug in is the problem, however i suspect that the builders of the plugin are correct, in that it is the way in design in handling images in links.
the problem is worse when any image in anchored any where with in the document.
when the updating links screen pops up, the point where it freezes and then indesign crashes is infact on a linked image file consistantly.
broswing other indesign link issues it appears i am not the only person with image link problems.
My question is aside form turning off the plug in, what else can i do to search for the potential issue?
InDesign doesn't normally crash updating links. If the problem goes away when the plugin is disabled, that's definitive.
