I just have seen new version posted on the download page and also tried about issue I’ve mentioned before.
Now the problem is gone I can view the file perfectly !
But there is another new problem for Thai language input in this new version (10.1.1).
Please have a look on video screen capture in this link.
The problem is, when I typing Thai upper/lower vowel it always shifted to the end of line. This behavior is not correct for typing Thai language.
But when I used copy and paste method to copy Thai text from Notepad to EmEditor, the program can display correctly.
Please have a look on this issue :)
