I've been configuring and testing HCL for a few days now, and I have a few issues that I can't figure out.  I'm hoping someone can help me, because to be honest my brain is fried. FYI - we're using 2.1.5

First, the application seems to freeze every once in awhile, and I have no idea why.  All of a sudden IE will hang, any tabs in IE will hang, and we have to close the browser to get things to work again.  This is our biggest issue - I can work around everything else.  It seems to happen if we do something in the admin area, but I haven't figured out what.  Booting the operators causes it for sure, but there are other times when I'll be udpating canned messages and/or operators and it hangs, and other times it's fine.

Second, the operators pictures disappear if you update the operator and don't re-upload the picture.  Does anyone know where I can fix this in the code?

Third - and this is in another post - operator chats don't work.  Customer chats are fine, but operator chats say "chat session has ended" to the recipient.

Fourth - when updating canned messages, we get these errors:
Notice: Undefined variable: operatorid in /homepages/37/d204568806/htdocs/marsvenus.com/public_html/www.marsvenus.com/hcl/class/canned.php on line 113

Notice: Undefined variable: departmentid in /homepages/37/d204568806/htdocs/marsvenus.com/public_html/www.marsvenus.com/hcl/class/canned.php on line 114

Notice: Undefined variable: messaage in /homepages/37/d204568806/htdocs/marsvenus.com/public_html/www.marsvenus.com/hcl/class/canned.php on line 116


Finally - more of a request - has anyone added or considered adding a FAQ page for things your operators need to know, but that aren't canned messages?

It's really intermittent - happened to me once, another operator today... other days we are fine.  It seems to happen only to operators, not customers - at least not that we know of.
