Cannot change channels in ad unit - bug?

[Oxydada]

I've been trying today to change a channel for an existing ad unit, but it doesn't change when I save it.
Also, when changing palettes it won't show the preview look (but it does save the colours if you try one by one - even if the preview won't show it).

Tried it in IE and Firefox, same problem - everytime I click on a color or try to add a channel (old or new), the page will go up and I have to scroll down again. When I save my edits, it will show the ad as edited today, but the channel is empty!

I've seen some people with the same problem in the Adsense boards today also, but that place is no one's land - nobody answers.

Any ideas? It's a bit difficult to ilustrate my problem in English, sorry.

Another weird thing: even if I'm trying to edit an ad unit, it will show features that are exclusive to link units, like rehash colors.

Thanks in advance for your help

Yes, I have the same problem, is started 2 days ago. It doesnt have the preview link either.

I have had (intermittent) problems adding new channels; the new channel is invisible (i.e. not appearing *anywhere*) and sometimes it will add a completely different, existing, channel to the ad block instead. Most frustrating. The only solution I found was to start the ad creation again from scratch.

i have the same problem here ! my channel disappeared and when i try to add the same channel again it says you cannot have duplicate channels the reason i am trying to recreate in the same name is Targeted placement this caused us to lose all targeted ads !

No one reply at Adsense help forum although many users reported this bug .. really annoying !

This is still happening, after 4 days.
Maybe ASA can help?

I'm getting this error in IE7: [translated to English]

Line: 775
Character: 3
Error: Invalid argument
Code: 0
URL: [google.com...]

This is really frustrating. I have to create all ads from scratch if I want to change channel cause I can't edit them.

I guess this is happening since the last maintenance and I just noticed 4 days ago, or maybe since that survey link appeared.

Any feedback?
