Using Matlab's posibility to search a file in the complete list of folders in the path leads to such strange effects. It is recommended to use absolute file names instead:
File = fullfile(cd, 'fp_database.mat');
save(File,'data');
...
delete(File);
disp(exist(File, 'file'))
The current directory can be modified by GUI or TIMER callbacks, such that absolute file names are more secure in general also.
