No I haven't noticed that at all.
Might be something up with your InDesign file - try File>export and choose IDML
Open the IDML and save it to a new file (IDMLs always open as untitled).
See if that fixes the problem.
If it's happening with all your files try reset your indesign preferences.
Do one of the following:
- (Windows) Start InDesign, and then press Shift+Ctrl+Alt. Click Yes when asked if you want to delete preference files.
- (Mac OS) While pressing Shift+Option+Command+Control, start InDesign. Click Yes when asked if you want to delete preference files
Now for the next part - why are you embedding your images? I know you can, but you shouldn't have to. Just curious why?
Also, I use PNG in InDesign files regularly and I've never had this issue.
Thanks! That was really useful
Thanks Eugene. I received the document in ID format with the PNG files linked and supplied separately. To try to work out was happening I created my own blank ID document and added the text from my own archived version but without the graphics. After the first save, this file opened and closed without any issues. As soon as I linked any of the png files the problem started happening. I then tried embedding to see if the problem was with linking, but the same thing happened. I then opened one of the PNG files in Photoshop and saved it, without any changes, in psd format, created another ID file with the same text, linked the PSD file and saved it. Re-opened it and closed it without ID prompting me to save. I also tried linking other PNG files from other sources, with and without transparency, in other ID documents. Same problem every time. Trashing my preferences doesn't make any difference either.
I don't often use PNG files, but I don't remember having had this problem before and I was wondering if it might be something to do with the latest version of InDesign (220.127.116.11 x64 Build). I'm not using any add-ons, font managers or anything like that, so I doubt that it's anything to do with my setup.
What OS are you using?
Sorry you said Windows 10 already.
I don't have those issues on Windows 10.
Out of interest, have you installed other software recently - or installed any peripherals?
I tried the same files on another computer with the same set up and they were fine. Reinstalled Windows 10 on the first computer and now they're fine on that too, so it must have been some sort of glitch in the Windows installation, but I've got no idea what. If I find out I'll let know, but in the meantime, thank you for your help.
