When working with text blocks in Interwrite Workspace I noticed that the length of the text lines were fixed to a short length. This happens whether or not you type the text or paste it in. I called eInsrtuction to ask if there was something obvious I was missing. The eInstruction representative noted the problem but did not have a solution. By playing around I found how to increase the width of the text block. Double click the text block if you are not in the text edit mode. Place your cursor on the right side of the text block. The arrow will change into a short left/right arrow. Drag the text box to the right to make it the desired width. This alone will not make the text box wider. You have to then click the right edge of the text box to make the text box stretch to that width.
The icons in the textblock window starting from the left are clone text, split sentence into words, change color, font name, font size, bold, italic, underline, left justify, center justify, right justify, bullet list and the onscreen keyboard.
I hope this helps.
