"save" dialog box not functional

[marcus aurelius]

I've been using ubuntu since 10.04. this problem seems to be in 11.04 as well.

1. save file
2. type in name of filename to use
3. after several characters, if any existing files match these letter, the entry field is replaced by the existing file name.
4. addition entry of characters is not possible

e.g.

1. i want to save the file as "mydocument details"

2. if a file called "mydocustuff" exists, after typeing "myd", the filename entry field is replaced by "mydocustuff". any attempt to continue entering the rest of the filename in 1. is prohibited.

i have to manually clear the filename field and re-enter the filename.

this is extremely irritating and non productive.

i would suggest that automatic "false" complete of the filename be eliminated when saving files.
