QM 2.4.0.1 : Item properties Programs list too short

[rkg82]

When I select the "Only" option for the programs I want to use my autotext macro with, the list box seems to be limited to 27 characters, which is far too short for the list of programs I need to declare. For example, I want to enter:
Authorit5,webuild,EditPadPr7,PowerGREP4
but QM will only accept:
Authorit5,webuild,EditPadPr
