Project Options Library (etc) Mystery

General Help
1

A mate was just seeing an issue calling out Spring4D.

He had a directory name change, and that affected the listed library paths, browsing paths, … (greyed out).

Fair 'nuf.

We went through editing each entry, turning like a ‘_’ into a ‘-’ or whatever … all good, bold black entries.

But on restarting 11.1, none of the changes took hold.

We experimented with just deleting the grey lines.
Delete. Ok. Restart.

Nope. Same. No change. O_o

PS :
Immediately after, we did remember to setup the Debug DCUs path.
That basically sorted the compilation issue.

And maybe the source path is somehow missing the .pas files (??) we’ll have to double-check.

But the not deleting dead lines still has me puzzled.
