After installing 3.0.16 whith GD 1.8.3, freetype support, T1lib, zlib, mysql
I got a problem which sounds so dump, that I thought twice to write it but it appears and is reproduceable.
I use php to change some data in a MS-excel 97 spreadsheet I use str_replace to change the data.
The whole file is read to the memory (it?s not as big 35k). Now the problem: while changing the desired data,
php changes also data which shouldn?t and the place is somewhere in the beginning and after the place
where the data should be changed (this will be changed correctly). 
I have a 2nd machine with 3.0.15 to compare with and it does not make this mistake als it worked until I changed
to 3.0.16
Any Ideas ???
