@uzapuca - I think you found a bug for us. It appears when you do the following you run into the bug:
Add text to an image (but do not save or click off of the text)
Export using the menu command
Image will export with any saved annotations, but not the text that is currently highlighted.
While we work on a fix here are a few simple workarounds:
Option A - Save your image first and then export <- This will ensure that all of your annotations are saved to the image.
Option B - Make sure you click elsewhere on the canvas after you've typed some text and then export <- This will deselect the text and allow for it to be exported.
Option C - Use the "Drag Me" tab at the bottom of the canvas window (Select JPG first if that is the format you need) and then simply drag to your desktop <- This method is working properly where all annotation objects are saved first before creating the file.
Thanks for finding this bug and pointing it out to us.
