Thanks, Kacy and Junglewoman. You're confirming what I suspected - that I'll have to get used to life without a few favourite old features, or look for new software elsewhere. The jury is still out.
Been a tricky day trading with Iress. There are a few features I like but I'm disappointed at how many more clicks I need to bring up info that on Pro Trader took a single click. Having to right-click 'Broadcast' every time I look at a security is plain irritating. Right-click buy and sell has been unreliable, too.
I'll give it a few more days and see how it feels.
