Version 3.8.34 had absolutely no changes in it that impact how files are imported. There were a few changes to the processing of chord pro files (and more are coming to handle emojis and other symbols like that). I have been importing many text and chord pro files without issue, so we will need to identify what is causing the issue on your device, or with your library. Making a new file and saving it should be almost instantaneous - if it's taking a long time, that points to a serious issue with the disk I/O. If you want to send one of the chord pro files you can't import to mike@zubersoft.com, I can try importing it to see if I encounter any of the same issues. If you are inserting any multi-character emojis in any of your files, then this may be related to the problems you are seeing. If so, that issue will be fixed with the next update which I'm hoping to submitted tomorrow.
