If you have a problem with a tool then restart from scratch and with a simple example.
1. In PSP 2020 I started a new document 800 x800 pixels white background.
2. After choosing the Text tool I reset it to default
Then change Points to Pixels, and make sure you have text as normal not bold or any previous choices.
3. At this stage my Text Tool Options looks like this
(1) shows the Text Allignment mode and (2) I also need to change the Stroke width to 0. Make sure Create as still shows Vector.
3. I type in a word and then click the Tick under Action to Apply Changes
A bounding box appears around the word and left clicking in the centre and dragging allows me to move the word(s).
Are you able to do all this or at what point does it fail?
