Insertion of images in text never completes succesfully

Insertion of images in text never completes succesfully

Hi all,

I am trying to insert images in a blank text (or any other text, for that matter) and after the (apparent) upload of the image, the text stays blank, with no image being displayed. Since it is happening in both Firefox and IE (and Maxthon) on my workstation, I believe that the problem is related to something installed and configured locally. Is there any kind of debug procedure, any log to watch, that you guys could recommend ?

Thanks

Marcio
