Text pastes as single paragraph when copying from external source.

Title says it all, whenever I paste text from any external source into InDesign, it pastes a single paragraph, getting rid of any line breaks and indents that were in the source. The issue does not occur when pasting the same source on a different computer. I have tried resetting prefs, uninstalling InDesign and getting rid of everything to no avail.

Thanks for the help,
