Zoran,
It looks like you are using Proj4js where it dynamically loads the
required projection code files. In some earlier versions of Proj4js
that had problems in IE (possibly in Chrome as well) but I think that is
fixed in the latest version. In any case, you can get around the issue
by using proj4js-compressed.js rather than proj4js.js which includes all
projection code. You can also build your own version of
Proj4js-compressed with only the projections you need and it would save
a little space.
