Problems with IE6.0 - buttons going inactive

We are encountering some bizarre behavior running our Servoy webclient application in Internet Explorer 6.0 (sp2) on Windows XP
I’m curious is anyone else has encountered bizarre happenings running under IE6.0

We are currently using Servoy 4.1.0 b3

Intermittently in our application the icons/buttons go unresponsive (note, both icons used for buttons and actual buttons themselves are affected). I can click on the icon/button and see the word ‘loading…’ in the corner for a split second but no action gets carried out.

I have seen the problem on ‘main’ screens as well as ‘pop-up’ screens.
I’ve tried on multiple systems - in two cases the problem was happening pretty often, on the one system we’ve seen it happen only twice over several hours of trying to make it happen. It’s important to note that all 3 systems have exactly the same version of software as these systems are prepped by corporate IT systems with a standard build procedure.

In every case the weirdness is the same… the icon/buttons just stop working - I say icon/buttons because we use little icons as buttons (but we have a few real buttons as well). I did discover that the only way to ‘unlock’ things was to hit the browser’s refresh button. If a pop-up had previously been displayed the ‘refresh’ would result in that pop-up going away.

The problem is so random I never know when its going to occur.

We don’t see this behavior in IE7.0 or Firefox (or even Chrome). Our client is stuck using IE6.0 (i.e. corporate standard) so I can’t do anything about that.

Do you see any errors in servoy log when this happens? Do you see any browser side javascript errors? I think the best thing to do is create a case in the support system attaching as much informations as possible.

We eventually found the problem… it was something called ‘Blue Coats’. This is some kind of network ‘sniffer’ software.
Once we setup the IP for the application server to be ignored by Blue Coats the problem went away sigh
