RunType being ignored

It is pleasing to be able to report that Iris and NetSurf are rubbing along a bit better now.
There is a small problem in that I can’t get NetSurf to be the default browser if Iris is running. Iris was run first and as expected double click on an html file means that it opens in the Iris window. However, Iris is still grabbing html files after NetSurf has been started. The html(FAF) runtype appears to be correctly set but is being ignored.

Alias$@RunType_FAF : /SCSI::SSD.$.Apps.N1.!NetSurf.!Run -html %*0

I think you will find that the Alias$@RunType variable is only actioned if there are no apps running that understand the filetype. Before that is done the wimp offers the file to currently running apps to load. It would appear that as Iris was run before Netsurf, Iris gets first refusal and grabs the file.

I have tried it both ways, ie NetSurf then Iris, or Iris then NetSurf.
Regardless of order or RunType setting Iris always grabs the file.
Does the wimp offer files to apps in alphabetical order?

Have a look at the !Boot files. It may be Iris is not following the specs correctly. In Netsurf !Boot it says

| We don't claim the URI filetype as the spec tells us not to:
| "Applications must not set an Alias$@RunType variable for the URI filetype"

However, in Iris !Boot we have

Set File$Type_F91 URI
If "<Alias$@RunType_F91>" = "" Then Set Alias$@RunType_F91 <Iris$Dir>.!Run --uri %%*0

Maybe this is the problem.

Thanks for the pointer.
Iris !Boot does test for empty values before setting, but not so the !Run file, or rather the !Run2 file. This goes ahead and sets aliases without testing for empty.
For now I have commented out the RunType setting in Run2 and Iris is behaving itself.
