I am testing a web-based inquisit task. I found that it runs flawlessly on a PC. But when I launch the same task on a mac (using either Safari or FireFox), the font size on the instruction page and the main task gets much smaller.

<instruct>

/ prevlabel = ("Press B to go back")

/ nextlabel = ("Press the spacebar to continue")

/ prevkey = (48)

/ nextkey = (" ")

/ fontstyle = ("Arial", 16pt, false, false, false, false, 5)

</instruct>

<defaults>

/ screencolor = (0, 0, 0)

/ fontstyle = ("Arial", 15pt, True)

/ posttrialpause = 750

</defaults>

I wonder if these tags work differently on a mac. On a mac, the real font size looks as small as 9 or 10.

Please help me figure out what the problem is here.

Thanks so much for your quick help as always.

This is a known issue and will be addressed in a future release. For the time being, try using percentage points for font sizes instead of point values.

Also don't forget that the screen resolution plays an important role. 12pt on a 1024x768 px 17'' monitor will not look the same as 12pt on a 1920x1080 15'' laptop screen.
