I still don't get the logic in version numbering so I may not have the 
correct version for testing the next release. I tried build 
"Lazarus-0.9.29-21480-fpc-2.3.1-20090830-win32" but experienced a problem:

When compiling I now get a warning that my project(s) do not use the 
unit "interfaces" and whether it should be added. I called this unit in 
the implementation part of Unit1 (but nowhere else) and it worked ok in 
earlier builds so I don't know why it suddenly complains about it.

If I choose to ignore the above warning it compiles just fine but for 
one of the 2 tested programs I am getting an error on startup: "Program 
could not be initialized correctly (0xc0150002)". It just worked fine 
with earlier builds. It seems that this a bug of the current build.

BTW: Recently Andreas Berger added persistent blocks (thanks again for 
that) but there are still some flaws with it:

1.) When continuing a previous search the next find is marked as the new 
block. That should not happen. Searching should not destroy the block 
settings.

2.) Copying a block with Ctrl+K/C works, but moving it with Ctrl+K/V 
does not. Nothing happens except that the block is no longer marked 
after that key.
