Thanks for clarifying! To help the author locate that problem, he may have some more need for details:
Which was the EmEditor version and bitness architecture (32/64) this works for you?
Which version and bitness do you use now you got this problem with?
Do you have EmEditor installed or do you use the portable version?
On which operation system (XP/W7/W8/W10) ?
Thanks for your support.
