Logged by: Ruediger Kemmler
Email address: r(dot)kemmler(at)gmx(dot)de
PostgreSQL version: 8.2
Operating system: Windows XP/Vista
Description: Installroutine hides destination folder
Details:
If you click first on the components which you want to install, the field
where the installation folder can be changed disappears and can't be
selected any more.
You have to go back in the installation routine to resolve it.
Minor bug, but can be problematic.
Kind regards
