Hi

I am having an awfully frustrating time using LyX. There appears to be a bug that continually produces a duplicate of a typed word (i.e. it duplicates words randomly throughout the document so that two words are repeated side by side).

For example, the sentence "The sky was very blue." could be typed and then later when returning to the sentence is is written "The sky was was very blue.".

I end up with lots of "the the", "was was", "to to" and repetition of other very frequently used words. However, it also happens with larger uncommon words.

Because my document is a thesis (using book class) and quite long, it is very frustrating. The absence of a grammar checker in LyX or spell checker that detects double words makes it a very tedious process to meticulously read to pinpoint every occurrence.

I have never actually been watching the screen when it has added a duplicate word so I don't know the circumstances that prompts it to occur. I did almost catch it once after writing a sentence and re-reading it immediately only to find that it had changed this

to

having duplicated the word hypothesis.

It is quite a ridiculous thing to have to deal with when writing a long document.

I'm currently using LyX 2.1.1 on Windows 7 primarily but also sometimes LyX with Windows XP. If there is anything I can specifically look for to pin point the cause I'm all ears.

That is one of the strangest bugs I have ever seen. I guess the first thing to say is that we have never had a report of this kind of problem, which isn't very helpful, but it does suggest that it might ben some strange threading issue. I suppose the first thing I'd do is suggest that you upgrade to 2.1.2. There were some bugs along those lines that got fixed in that release.

If that does not help, then hopefully someone here will have some ideas.
