Setting SetTextOverlayIsVisible(true) and SetTextOverlayHoldTime() to any value (including 0) causes the SlideShow component to just spew isPlaybackPosition events while the image doesn’t change (the index returned is always 0).

Thanks for the bug report. I’ve confirmed this bug was introduced in v2.8.
We’ll have a fix in an upcoming release.

I believe I’ve hit a different bug related to this one. If I use SetTextOverlayIsVisible, the slides do not auto advance. Here is how I create the slideshow
slideshow = CreateObject(“roSlideShow”)
slideshow.SetMessagePort(port)
slideshow.SetPeriod(6)
slideshow.SetTextOverlayIsVisible(true)
With the above, the next slide will not display after 6 seconds, but will if I remove the SetTextoverlayIsVisible call. I also tried setting SetTextOverlayHoldTime, but that doesn’t seem to work (the overlay stays forever) and has no effect on the SetPeriod.
I’m running version 3.0
(edit - hmm, seems like I just recreated the same problem. I should have read the original post more closely 
Is this still scheduled to be fixed at some point? I see it was reported back in 2.8 and still exists in 3.0. I’d like to use the overlay in slide shows, but it isn’t usable as it stands now.
Thanks,

I see the exact same bug. Seems it has been the case for quite a while based on the history of this thread. Is there an ETA on when it will be fixed?
It basically makes text overlays unuseable.
A workaround is to not call SetTextOverlayIsVisible(true) and just set the time with SetTextOverlayHoldTime(). I just tried it on 3.1 and I believe it works on 4.1 as well.

Great find, and thank you!

Any word on this? I’m still reproducing this bug on 4.9, and calling SetTextOverlayHoldTime() isn’t overlaying any text for me.
