after a bit of research, this issue is related to Safari and ie browsers. I believe it's been patched in one of the assets updates I did for ubbt762. later today I'll send you a direct link in pm with the file archive needed to fix this this on your forums. for everyone else, this fix will be part of the upcoming ubbt 762 release.
again, thanks for your quick follow-up and mainly for posting about this issue. everything helps
