I have the same problem with IE version 8 (Windows xp). Yes I know that it’s no more supported, but many of my customer still use that one.
Check it directly on my site: https://www.dlanet.it:9081
In other browsers/versions I don’t have any issues.
Please help me to solve or tell me how to come back to previous version (1.4.4) or (1.4.3)
Thanks
