Product Categories Tree yields "error loading callback data"

In Admin, I added several empty categories and sub categories to the bottom of my categories. When I find a product and access its categories, the bottom subcategories won't display correctly. When I click on them, I get a popup message that: "error loading callback data".
I added the following:
Visi Parent
Visi Child1
Visi GrandA
Visi Child2
Visi GrandB
When I first display the product's categories, it just shows Visi Parent. I can click on Visi Child1 and it will expand to show Visi GrandA. But if I click on Visi Child2, it displays the error message and won't display Visi Grand B.
I was able to repeat this several times in a row. I tried repeating it again while typing this up and of course, this time it worked.
Even so, is this a known problem?

Not really. Could you provide some screen capture to elaborate your problem.

Unfortunately, it's stll working. (I just tried to repeat the problem without it happening.) If it does happen in the future, I'll try to document it.

My apologies for resurrecting the dead so to speak...but this issue is occuring for me as well. When trying to connect the products to categories and we get the "Error loading callback data" pop-up when drilling down to select the proper subcategory.
Any ideas as to what may cause this?
Using Able v7.02
Thanks in advanced.

We also have a client having this problem when trying to add products to their catalog.
Sometimes see this error message when working in the admin tool: "Call back error"
And we are not allowed to place the products into categories, next visit it will be gone - what is this message?
It is having a major effect in slowing down our ability to get products loaded into the catalog. We have not been able to see any pattern to when the site will throw this error. For example, we will have successfully loaded 3 items then the fourth will have this message and we need to stop, note the product that could not be loaded, then come back to it later. When we come back to it, it will load correctly.
It sounds to me like an issue with their PC communicating consistently with the web server, but we haven't been able to replicate it locally. Does anyone have any more information about this?

I've started searching on this and found one post in the ComponentArt forum:

I was looking thru some logs for something else and the site we are having problems with had this in the log file:

I had suspected special characters in the name yesterday, but hadn't checked the logs because I didn't have specific feedback from the client as to the procedure that caused it. They have / and " in some of their names.

Judy,
I'm not sure special characters are causing this since they say it's frequent, but not repeatable. So sometimes it happens when they're trying to add products to categories and sometimes it doesn't. And the categories it happens to are different each time. When they have a problem adding a product to a category it'll work fine if they try again in a few minutes.
I would expect it to happen all the time for a specific category if it was related to special characters in the name.
