Occasionally I have unremovable breakpoints. I think it may occur when I attempt to remove a breakpoint from a line which is currently executing. When the build has stopped, I’m left with a breakpoint (red square) on a line. I click it, it flickers briefly, then reappears.
Interestingly, F9 makes it disappear.
Ah, on closer inspection the problem seems to be adding/removing a breakpoint by clicking on the currently-selected line. I can click any other line and create/remove a breakpoint. But not on the current line.
Build 201 btw.

looks like it’s a bug in the tree view - will investigate.

Actually it seems that clicking in that column always produces incorrect behaviour. Sometimes it makes a “fake breakpoint” (a little red arrow) show up. Sometimes a breakpoint flickers then goes. Sometimes it stays, then can’t be removed. Using F9 always works.

Vincent was looking at this yesterday, and it is indeed a bug in the treeview component. No solution yet though, but hopefully soon.

That’s cool, it really has no impact, as F9 always works.

For the Delphi keyboard style users, F9 should be read as F5!

True 😉
(I would love to know how it worked out that MS and Delphi ended up using F5 and F9 for run and set breakpoint, but with the meanings reversed. There was a time when I was doing a lot of VB and Delphi, and it never failed to confuse me.)
