Hi, I just found sublimetext but have problem saving.

I am using Windows 8.1 64 bit.

ERROR:

Unable to save <path> Error: MoveFileEx(path) failed, The file is locked by another process.

I can open the file in another editor and save without error.

was about to report the same, found this: github.com/SublimeText/Issues/issues/379

basically, you must turn off atomic save which is a very buggy feature
