Problems with Fat32Fs and the command line

Hi,

I have a problem using the command line with Fat32Fs on an Iyonix 5.18.
If I use the desktop to set the working directory to the root of a drive, open a task window and then type “*cat” then Fat32Fs is asked to enumerate the directory “:HD-PCU2” (just the drive name) rather than the expected “:HD-PCU2.$”.
If I type “*cat pda” then Fat32Fs is asked to enumerate “:HD-PCU2.pda”
If I type “*cat $.pda” then Fat32Fs is asked to enumerate “:HD-PCU2.pda”
If I type “*cat :4.$.pda” then Fat32Fs is asked to enumerate “:HD-PCU2.$.pda” (CORRECT)

Is there anything that Fat32Fs could be doing to provoke this behavior?

Below is a log of the calls that RiscOS makes to Fat32Fs:
