The TEXT is causing the left column width to grow. You can either set a fixed column width in the options or set wide:1 and use display: instead of text:
text=font-size:120%,color:0000FF,wide:1,display:Warning: Your computer …
or use the COMMENT item:
comment=font-size:120%,color:0000FF,display:Warning: Your computer has …
which is essentially the same thing.
The code around the IF / CONTROL items is not perfect (shock!). The IF doesn’t evaluate on startup causing the CONTROL to display and during the normal cycle when the IF does evaluate, it fails to switch off the CONTROL.
Add “onload:1” to the IF item to force it to evaluate during startup but that won’t help once the condition changes.
I’ll raise an issue to fix that bug.
