thanks a lot. I did all according to your instructions, even reinstalled Comodo Dragon, removed all extensions, did the same procedure with my 2nd laptop but it didn't work with either of 2 laptops. there is probably some conflict with one of installed programs but which one (there are too many in my computers)? Strange thing is, if there is some conflict between any of installed programs and Comodo why it is not the same case with other browsers (especially with Chrome) ?
Comodo is very, very fast (seems faster than Chrome), takes much less space (69mb) than Chrome (163mb) when installed and maybe it is the reason something is missing in Comodo to show full graphic like other browsers.
