uVision4, floating editor windows with full path displayed ?

Greetings all,

I recently updated to MDK-ARM V4.22a (because the trusty old version didn't support LPC1788).
It's registered version, new PSN, new LIC, all ok so far.

But I cannot compile existing projects anymore (written in uVision3 some years ago, and I prefer the old IDE for various reasons).

Compile a project in uVsion3 isn't possible anymore, with the following error message:

> Compiling xyz > --- Error: failed to execute 'BIN40\ARMcc' > Target not created

uVision3 + uVision4 both correctly show the new toolchain in the about box.
But only uVision4 seems to be able to invoke the ARM compiler.

Any ideas why ? Has support for uVision3 been dropped completely (would be very sorry for it).

Then loaded the exising project (*.uv2 !) in uVision4. Compiling works, after the usual modifications in Keil's RTL.H (removal of Keil's TCP/IP stuff because it collides with LwIP).
Compiling+linking works with uVision4 (but as usual, the code doesn't work anymore because my custom startup code is incompatible with the current runtime library / kernel.. sigh...).

The tabbed editor windows in uVision4 are quite annoying. I'd prefer to have freely floating windows as in uVision3 so I can place those windows where I want to have them.
Any chance to have 'freely floating windows' instead of the tabbed or "split" windows in uVision4 ?

Can the full path (not just the filename) displayed in each of the editor windows, as it was in uVision3 ?
(Reason: I have dozens of files with the same name, but a different paths (typically something like 'config.h', which contains project- and/or hardware specific settings) .
Ok, I can point the mouse somewhere and uVision4 shows the path in a bubble, but that's not as good as simply having the full path displayed in the editor window's title bar.

All the best, Wolfgang .
