Hi. Any update? I'm still having issues even when I upgraded on the latest version.

Thanks!

hello. I tried all your suggestions on #3 except for

1. you can check if there are javascript errors in IE by looking at left bottom corner of browser window (if there are errors there will be one icon and some text with information that errors occured). - I did not find any actually. I even installed the IE Developer tool but did not find any error.

2. You can also check in server logs if there are errors, but in this case I think this is related with js. - unfortunately, no errors on logs.

3. Please try if your problem occurs on demo page http://ckeditor.com/demo. - I tried it on IE9 and I have no issues when I tried to click the Source and edit the content there.

4. If not please install latest drupal dev release and check it. - are you pertaining to the Drupal Core?Just verifying.

5. If last step doesn't help please check if this is not related with some of module installed in your drupal. - I disabled all contributed modules but the problem remains the same. The source remained freeze. =(

* I've also tried disabling/enabling the module. But haven't tried uninstalling it.
* I've tried it in my sister's laptop that is still using IE 8 and the I can edit from there. Argh...

Any other input will be very much appreciated.

by the way, I'm using IE9 and Windows 7 Home when I try to edit the content. In IE9, it text area freeze.

@michal_cksource. I already updated the module to 1.3 but the issue is still there. We have two machines that is Windows 7 Home Premium, 64Bit and IE9 and both of them freezes when "Source" from CKeditor is clicked. But not when we try to "Switch to plain text editor".

I have three people tried editing one of our content, they are all using IE8 and they have no issues.

@dczepierga. We have our custom theme but I'm not sure if it's related since we have that theme ever since. It's only now that we have issues on this. If it's the theme's css. How do I check what causes the error? I've already switched the theme to use Garland but it still freezes.

Now, I'm thinking this can be an isolated issue on IE9. I have disabled all plugins in my IE browser and yet no success. Good thing, editing using other browsers is working.

is it safe to say that I'll just wait for it to correct itself?... =)

@michal_cksource. I've tried CKEditor 6.x-1.3 in a new fresh drupal installation in my local. The CKEditor worked and it did not freeze when I try to edit it via "Source".

for now, we have decided to revert our IE version to 8.0. We have no issues now.
I'll let you know once we find out the solutions.

hi dczepierga! I just checked my IE9 today and now everything works as it should be. I don't know what solved the issue actually as I was not able to track any update on the website. I think reporting that it works now is not that helpful because the real cause and fix has not been recognized. Anyways,I just thought you might want also to know it....

Thanks all for your assistance.
