Blank Screens often in backend...Contao 2.9

[ramjet]

Hi All,
Since updating to 2.9 I often get almost blank screens in Firefox 3 when I do things in the backend like save a record or make a new record etc.
I say almost blank because the title shows in the browser but nothing else.
Strangely...if I "view source" all the html of the body exists, but if i inspect the blank page with Firebug it shows empty body tags, and its empty to look at.
No errors are thrown.
This is intermittant, sometimes it comes right, but I'd guess it happens 25% of the time.

I'm going to check on the demo, and see if it happens in other browsers, but in the mean time has anyone else noticed this???
Its only started happening since upgrading to 2.9


UPDATE:
COULD A MOD PLEASE SHIFT THIS TO THE DEVELOPMENT FORUM...
This actually only affects one module I have made,especially when creating a new record, and only in Firefox.
I 've updated firefox, cleared everything in all caches,turned caching off, cleared the browser but the problem persists.
Anyone have any ideas???

Unfortunately refresh doesn't help for me.

I've noticed this in firefox for all versions. Usually if I hit the back button in my browser and then try to edit the page again it works. Also, I've only noticed it in firefox running on mac and haven't had any problems with firefox on the PC.

I'm seeing this behavior intermittently in all installs of Contao 2.9.0. 25% of the time is probably correct. This behavior seems limited to Firefox, but IE 8 crashes so frequently that I generally don't use it for maintaining Contao sites. I'm on a Windows 7 Professional 64-bit desktop system, Linux / Apache server for the Contao installation.

Refresh does not solve the problem, I have to hit the back button and then click on the action link again to clear this error.

Very annoying especially during an online demo of the Contao feature set.

Anything remarkable in /system/logs/error.log? Activated "Show error messages"?
